A common mistake then reprecenting pixel positions is to use Integers. This is how we did things back in the 80’s and 90’s, but GPU’s use double and pixel 1.5 actually exist. As the GPU smooth lines it will add shades to make it look as if we have pixels between pixels. If your coordinate…
The reason I don’t want to copy pre-made gauges is because I want to create the gauge layer by layer and then have the option to stack whatever Gauge I want. WPF provide a few graphic shapes like Ellipse, Line and Rectangle, but the rest you need to add yourself. This one is a Pie.…
Working on BSA I have been through a lot of work to style common controls in WPF and QML to make SDK’s I can use as I generate code. Most of this work was doing the designer part in BSA, but in some cases I also had to create the controls themselves from scratch. Starting…
This ModbusTable is only 100 entries and behaving very nice due to a trick where I only load row details if the row is expanded.That trick will allow me to create tables up to ca 300 entries and still have decent behavior, but it is no solution for very large tables. So I will need …
I am very pleased with how I integrated Modbus as far as the result goes, but it has been a bit of hand-tailoring inside BSA – I am not so happy with the later because that is not a generic solution. So I need to find a way to create user controls the same way.…
This shows BSA with a 64 register ModbusTable. You will recall that I had some performance problems earlier with loading large tables into my property editor. This one takes ca 5 seconds to load, so it is getting very annoying to work with. The reason for this is because I load ca 1216 user controls…
This diagram is a bit messy, but it is fully legal. You see local variables in top, left corner. You see PLD State symbols in green and Magneta, You also see addign and events used to execute if tests. PLD State symbols originate from SDL (Specification and Description Language) that is popular in telecom and…
This example show the actual, finished Select component. I have set OnOK = Mandatory to show how it will look like. This means that you need to connect OnOK. But, I also added Parameters on top and description below – user can control both. I am quite happy with the result because this makes code…
Reading/Writing Modbus in BSA is very easy. You define a ComLink a set it to Auto – just specify parameters (that I forgot above). the parameters will in this case be fixed as you need to connect Open to set them. Define modbus Tables. Each modbus Table define an area of registers that are connected…
As you can see the Arrow to the right miss the Connection point as I resize that symbol. This exact bug was hard to understand because all calculations was correct as I examined the code. But, then I noticed that the line always adapted to the previous CP position as I resized the symbol. CP…
